# FTSE MIB: What It Measures and How It Is Built







## Direct Answer



> The FTSE MIB is a rule-based measurement of major italian equity benchmark, maintained by FTSE Russell/Borsa Italiana. Like every index it owns nothing: it is a number produced by applying a published weighting formula to a selected list of companies, revised on a schedule the provider sets.








## What this index covers



The FTSE MIB covers major italian equity benchmark, within the Italy market. FTSE Russell/Borsa Italiana defines which securities are eligible, how they are selected from that pool, and how much each one contributes to the published number.



The index name does not state a fixed company count, so the number of constituents follows the eligibility rules rather than a target.








## How constituents are weighted



Swoopr has not verified the weighting method for this index against FTSE Russell/Borsa Italiana's current methodology document, so none is stated here rather than guessed. The provider link below is authoritative.








## Current FTSE MIB constituents



FTSE Russell/Borsa Italiana publishes and licenses the FTSE MIB constituent list. Swoopr does not republish it here. The provider's own page is the authoritative source for current membership and weights.
